17325-02-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 17325-02-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,3,2 and 5 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 17325-02:
(7*1)+(6*7)+(5*3)+(4*2)+(3*5)+(2*0)+(1*2)=89
89 % 10 = 9
So 17325-02-9 is a valid CAS Registry Number.

Acid-promoted rapid solvent-free access to substituted 1,4-dihydropyridines from β-ketothioamides

Li, Ming,Sun, Ke-Na,Wen, Li-Rong

, p. 21535 - 21539 (2016/03/08)

β-Ketothioamides (KTAs) have been used as building blocks with aldehydes and β-enaminonitriles for synthesis of 1,4-dihydropyridines in the presence of AcOH under solvent-free conditions within 5 min. This new strategy exhibits remarkable features such as high chemoselectivity, mild reaction conditions, easily available substrates, and good yields.

Rhodium-catalyzed asymmetric hydrogenation of β-acetylamino acrylonitriles

Ma, Miaofeng,Hou, Guohua,Wang, Junru,Zhang, Xumu

experimental part, p. 506 - 511 (2011/06/17)

The rhodium-catalyzed asymmetric hydrogenation of β-acetylamino acrylonitriles was investigated by using monophosphine and bisphosphine ligands. It was found that an Rh-QuinoxP complex exhibited high enantioselectivities for β-aryl substituted β-acetylamino acrylonitriles and the Rh-JosiPhos CyPF-t-Bu complex was proven to be effective for the hydrogenation of tetrasubstituted olefins from cyclic β-acetylamino acrylonitriles.

Addition of acetonitrile anions to unsaturated systems under ultrasonically dispersed potassium system
